If you dont have the time or the means to let a dog run atleast two miles a day then you shouldnt own a dog. Any breed that cant easily run two miles isnt much of a dog and you should look into getting yourself one of them. This isnt from personal experience but I've read that bull mastiffs are generally very short lived and plagued with poor health. So much so that one person who loved the breed dearly said they'd never have another because they couldnt stand the heartache that came with them. An American bulldog will die for its family without hesitation but need exercise to remain mentally and physically healthy. Two miles a day would be a minimum and they'd do better with ten at their own pace. For a look at what an American bulldog or Pitbull should be if bred properly then do a web search for Southern Bulldogs. I'm not affiliated with the this kennel in any way shape or form.

Strange, how whenever the name Bullmastiff comes up, there are quick responses that seem to somehow put out the fire before it has even started. With all respect, Vinay(bullmol242), I totally understand what you are saying, I respect you as a breeder, and have always commended you and still do to this day. What you say is very true , that the Bullmastiff has been 'watered down', but, I firmly believe from my own experience, that there are truly outstanding specimens, who will guard and protect in many different situations, while still very young, and above all, with no formal training. From what I have learned from Bullmastiff owners from the the US, is that they have far less drive, than the Bullmastiffs in the UK. I think, personally, that whenever, such a question is posed, people will take it personal and try and promote their dog of their country. I am speaking from experience, and can honestly say, in reply to Cornelio, the Bullmastiff is a great guard dog, fantastic with children and babies, other pets, if introduced when young, and require basic exercise. With regards to life expectancy, it all depends on genetics and how well you take care of your dog. I got to meet my dogs grandparents, parents before we bought our Bullmastiff, and they are still alive and well. I really think generalization is a bad thing, just look at the AMERICAN PIT BULLTERRIER, so many bad things said about it, and its a great breed of dog. There are bad lines out there, and there are good ones. I think this can be argued about a lot of Bully breeds. This is just my opnion from experience.

I am a newbie with my American Bulldog, who I do have the pleasure of sharing his life with my family for over one year. First of I do not run 2 miles a week with my dog. I should for the reason I need to drop weight and not because he is hyper. When I first got him we walked for an hour 3 times a week in the evenings, but since he turned 2 we haven't done that much walking. I do have over an acre of land where he does run around several times a day. He is not a outside dog. He loves to be with us. You will need to do OB training with this breed. They bond very well with their family members and their friends. Spike evens has accepted the family cat and the other two dogs we have. American Bulldogs are active and may have a high prey drive depending upon their breeding. I am still learning about this breed. I do love ABs

I guess I am spoiled from being around working AB's. Because I would never call an AB a dog that was friendly and permissible with strangers or other animals and would never classify them as low enough in drive for the normal suburbanite or city dweller. And as far as country bred AB's go, Ive never heard of one that will tolerate same sex dogs. From my experience they will tolerate strangers when the owners are around but they don't care for them and are easy to set off. And they are normally zero tolerant of free roaming males. And have full blown hella-drive. And are much better mannered and managed when they are tired out from work or play as any dog is. So once more, ask the breeder of your choice questions about his line and common disposition and temperaments. I have met one scatter-bred AB that was a really friendly out going dog with strangers, in my mind very un-AB like, but thats because Im hooked on a certain line of AB's and I am biased. Each person here will have their own personal opinions of what makes a good dog or certain breed, best thing is don't mistake AB's as low drive and Labbish in temperament, most are not, and thankfully they haven't been recognized and destroyed as a show breed...yet. Once more ask questions of the breeders you are looking at about their line of AB, you could end up getting a dog you can't handle. Good Luck!!!!

well, considering there is a great deal of each breed in the other, your pretty much just depending on the ratio of ab to bm as far as type, temp, body, health etc etc etc
